3 phases of CVA or Stroke - ansPrevention
Event
Recovery
20-25% of strokes are due to - ansinactivity
87% of all strokes are? - ansischemic strokes
A patient has a SAH what are they now at risk for? What should you as a
nurse pay attention to? - ansVasospasms
Acute treatement of stroke patient arrives at ED - ansRAPID triage, lab work,
Non-contrasted head CT, NPO, treat hypertension if necessary. 3 HOURS for
Iv tPA 8 hours for Arterial tPA
After a hemorrhagic stroke what happens - ansthe pressure in the brain rises
resulting in an overall decrease/reduction in blood flow to brain.
ICP increase
All potential causes of ICH stroke - anstrauma, anti-coagulants, cocaine,
vascular malformations (AVM), brain tumors
Cardiac causes of a stroke - ansA FIB
A- Flutter
cerebral ischemia - ansInadequate supply of blood to the brain
Also cerebral hemorrhage
Computed tomography angiography (cta) - ansComputed tomography
angiography (CTA) uses an injection of contrast material into your blood
vessels and CT scanning to help diagnose and evaluate blood vessel disease
or related conditions, such as aneurysms or blockages.
,Biochemistry Final Exam - Portage Learning
CVA - anscerebrovascular accident (stroke)
Deficit progression of thrombotic stroke - ansbecome progressively worse
and may wax and wain
patients have
Diagnositc Studies after stroke - ansCT
MRI
PET
angiogram
Doppler
Embolic Stroke (Ischemic) - ansa clot is formed in one place and then travels
to occlude a blood vessel in the brain
hemorrhagic stroke - ansoccurs when a blood vessel in the brain leaks or
ruptures; also known as a brain bleed. Blood leaks into surrounding brain
tissue
how long after a SAH is a patient at risk for vasospasm - ans6-10 days
how to diagnose a Subarachnoid hemorrhage? - ansCTA (Computed
tomography angiography)
Angiography
how to treat subarachnoid hemorrhage - anscoiling or clipping the anyeryms
How would you assess a stroke - ansNIH stroke scale
ABCS
Infarction - anssudden blockage of an artery, death to tissue
Lease common type of hemorrhagic stroke - ansintracerbral
Major risk factors of a stroke or cerebral vascular accident (CVA) -
ansUNcontrolled hypertension
diabetes (DM)
,Biochemistry Final Exam - Portage Learning
Atril fibrulation or flutter
stress smoking obesity ETOH/ cocaine use
oral birth control use
AA race
management of intracerebral hemorrhage. (Main focus) - ansTreatment
aimed at ICP control and evaluation
Management phase of stroke, what are the modifiable risk factors for 90% of
strokes? - ansDM, ETOH, psychosocial factors,the ratio of apolipoprotein B to
A1 (highCHOL and lipids), cardiac issues A-fib, A flutter and valve disease
hypertension smokeing abdominal obesity diet, 20-25% of strokes are due to
inactivity
Previous MI
medical mamagement of ischemic stroke - ansThrombolytic therapy (t-PA)
Most common cause of a hemorrhagic stroke - ansuncontrolled hypertension
most common type of ischemic stroke... - ansThrombotic Stoke
NIH stroke scale - ansA tool used to objectively quantify the impairment
caused by a stroke
Composed of 11 items, each of which scores a specific ability between a 0
and 4.
For each item, a score of 0 typically indicates normal function in that
specific ability, while a higher score is indicative of some level of impairment
Individual scores from each item are summed in order to calculate a
patient's total NIHSS score.
Maximum score is 42, minimum is 0 :
0 = no stroke symptoms
1-4 = minor stroke symptoms
5-15 = moderate
, Biochemistry Final Exam - Portage Learning
16-20 = moderate to severe
21-42 = severe
Presence of blood in CSF - ansmay be a sign of hemorrhagic stroke - but, not
diagnostic
prodromal strokes - ansministrokes ususally end up leading to a thrombotic
stroke
Progressing stable stoke - ansTIA, transient ischemic attack
This can be included in a cerebral vascular accident
Side effect of t-PA - ansCerbral Hemorrage
SP. SAH tests and risks of test - ansLumber puncture
Presence of blood in CSF may be a sign of hemorrhagic stroke - but, not
diagnostic
Contra indicaed in the precene of IICP >15
So CAT scan first b/c of herniation
Stoke Signs and Symptoms - ansOne sided weakness
Numbness/paralysis of face, arm, or leg
Blurred vision in one or both eyes
Difficulty speaking
Slurred speech
Facial drooping
Loss of balance/coordination
Severe headache
Stroke occurrence the physiology - ansa blood clot enters the cerebral
circulation, blocking an artery and causing the death of brain tissue.
Inadequate supply of blood to the brain (cerebral ischemia) or cerebra
hemorrhage with in the brain
